The prompt was to create a handheld metal object no bigger than 6" based on continued explorations of metal connections
My handheld tinplate object is an assembly of different connections between subordinate and dominant trolleys, trolleys and cylindrical rings, wires and trolleys, and rings and wires, creating an ecosystem of relationships with surprising functionalities. The limitations created by the wires, the size of the rings, and the width of the trolleys lead to constrained ranges of motion that are nonetheless practical. These parts are essentially functioning as tracks, rotating or revolving mechanisms, and modular systems. These constraints allow a designated, specialized function, narrowing it down to a particular use — rotating, moving, shifting — in relation to other parts.
Process
(1) Initially, I began by developing the trolley connection on paper as a sketch.
(2) I was thinking of ways to make two parts lock together and create a track.
(3) Based on suggestions, I then refined it and made  the connection by welding two smaller parts together and connecting it to an outer layer in the shape of the parts, locking in and creating a trolley.
(4) The Trolley!
(5) Then, I explored different options to attach it to a track, such as with detents.
(6) I created an axial cylindrical system with numerous tracks that was an attempt to create greater range of movement.

(7) Then, I explored, based on suggestions from critique, a cylindrical track, something that would aid the exploration of a question I had since the beginning of the trolley invention: how to create a greater or constrained range of movement for the trolley.

(8) developed a way to make rivets for the different parts and attach them without damaging the pieces and for making the connection strong. I used vice breaks based on suggestions*.
(9) Strong Rivet Connection!
(10) Initially, I made a single ring-trolley-wire assembly, then increased it to two assemblies based on suggestions, creating another relationship by varying the connection point of the rings and trolleys in a binary system: ring 1 connects to ring 2, ring 2 connects to ring 1.

(12) I thought that that was the end to the whole development, but I was also wondering how it might behave with additional rings-trolleys-wires. I found a way to create an additional relationship by exploiting the network of rings as attachment points for another ring-trolley assembly: ring 1 connects to ring 2, ring 2 connects to ring 1, ring-trolley assembly 1 connects to ring-trolley assembly 2, ring 3 connects to ring 4, ring 4 connects to ring 3.

By repeating a connection in a ring, making two trolleys connect together, I could duplicate the amount of connections. I am sure that I can continue doing so indefinitely*. In this way, I was able to achieve my goal: to allow a greater range of movement for the trolley-ring assemblies!

For the final version, I hemmed the edges and used dividers a lot more for more accurate, precise, clean measurements. I used templates to make mass-manufacturable items.
